SP'INDLE FOR LOOM-SHUTTLES.

SPECIFICATION forming part of Letters Patent No. 233,388, dated October 19, 1880.

Application tiled January 6, 1880.

To all whom it may concern:

Be it known that I, HENRY A. WILLIAMS, of Taunton, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Spindles for Loom- Shuttles, (Case B,) which is fully described in the following specification.

This invention is an improved contrivance of the binding spring or springs employed in a loom-shuttle for fastening the cop on the spindle, so as not to be displaced by the shocks to which the shuttle is subject.

It consists of one or more springs located in a slot of the spindle and ranging longitudinally therewith, the ends thereof next to the point of the spindle being fastened, while the other ends rest loosely in a hole or bore extending from the slot in which the springs are to the base of the spindle, where it terminates in a slot, in which latter slot and bore there is located a push-rod, against the end of which the free ends of the springs are thrust when the spindle is shut down in the shuttle with the cop on it, and are thereby so contracted in length as to be bowed out side- Wise along the slot of the spindle and pressed against the cop.

The push-rod is a steel spring, which springs forward and backward with the spindle as it is raised out of and shut back into the shuttle, and in bending or springing outward when a new cop is to be put on it, retracts somewhat from the binding springs, whereby they are released from the thrust of the pushrod against them, and, by longitudinal extension, relax their lateral pressure so as to allow the cops to go on the spindle freely.

Figure l is a longitudinal section of a shuttle with the binding-spring contrivance arranged according to my invention, and the spindle being closed down in the shuttle. Fig. 2 is a similar section with the spindle raised up, as for applying a cop.

A represents the spindle, which is pivoted at B in the shuttle C, and is provided with a spring, l), to set or hold it either in the open or closed position, as shuttle spindles are commonly arranged.

E is the slot in the spindle in which the binding-springs F are arranged. In this ex- 5o ample I have located said slot near the point of the spindle, where I prefer to have it; but it may be in the middle portion or near the base, if desired.

The springs F, which range lengthwise of the spindle in order that they may be bowed out, as in Fig. 1, to bind the cop, are conned and secured at the ends G, next to the point of the spindle, while the other ends, H,

extend across the slotinto the bore again at 6o the other end of said slot, wherein they rest with their ends against the end of the pushrod therein.

The push-rod extends beyond the lower or base end of the spindle into a socket in the metallic shuttle point K, which is in line with the bore of the spindle when said spindle is down in the working position in the shuttle.

The base portion of the spindle is slotted 7o at L, below or back of the pivot B, to permit it to swing up for receiving the cop without cramping or bending the rod, so as to endanger the breaking of it.

Now, it will be seen that when the spindle is closed or shut down in the body of the shuttle, the free ends of the binding-springs will be thrust against the end of the pushrod, which will bow the springs out through the slot and cause them to bind the cop. 8o

is eccentric to the axial line of the spindle and push-rod when down in the shuttle.

When the spindle is raised out of the shuttle for shifting the bobbins, the distance between said points increases so that the springs are freed from the push-rod, whereby they 9o contract and allow the bobbin or cops to slide on or off freely.

I claim- 1. The combination of the binding-springs F, and the push-rod J, with a loom-shuttle spindle which is made hollow and slotted, as

describeiLto revolve the same, substantially as tudinal axis of said rods and springs when spxciid. in the Working position, substantially as de- 2.
